... Stability The IRU1260 requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. Typical designs for the microprocessor applications use standard electrolytic capacitors with typical ESR in the range 100mV and the output capacitance of 500 to 1000mF. Fortunately as the ca- pacitance increases, the ESR decreases resulting in a fixed RC time constant ...
